RE: Help with imaginary number output from CAS
I have noticed that same "_x" returned with a couple of expressions to be solved as well.

While I don't know why it shows up (maybe someone from the HP team knows more), what helped me in those cases was to specify an interval for the solver (e.g., x=-2 .. 2 instead of just x), which returns the solution [-1 1] without any problems (with "complex" checked).

[edit: in your case that would be w = -2 . . 2].
